To determine how many angles are adjacent to angle DOC, we need to know the context in which angle DOC exists. Angles are considered adjacent when they share a common vertex and a common side but do not overlap.
If we assume angle DOC is part of a complete figure, like a polygon or at the intersection of two lines, typically, there would be two angles adjacent to it—one on either side of angle DOC.
Without additional context or a diagram, the most common scenario is that there are two angles adjacent to angle DOC. If you can provide more details or a specific figure, I could give a more precise answer.
